MIG solid wire uses a voltage sensing (VS) feeder that does not require a control cable
FCAW (Flux Cored Arc Welding) uses a voltage sensing (VS) feeder that does not re-
quire a control cable back to the welder/generator.
Stick welding with or without a remote amperage control. Strike an arc to start welding.
Lift Arc TIG: touch tungsten to work and lift to start welding. Uses circuitry internal to the
welder/generator to aid arc start. Can be used with or without a remote control.
High Frequency TIG or Scratch Start TIG welding. High frequency TIG starting with re-
mote foot control allows remote On/Off and Amperage control. Another typical application
is a simple TIG rig with a remote control device.
Stick welding with RFC-14 control allows remote On/Off and Amperage control. This can
FCAW using a constant speed feeder. Use feeders with remote voltage control, or use a
MIG solid wire using a constant speed feeder. Use feeders with remote voltage control, or
1 Process/Contactor Switch
!
Weld output terminals are ener-
gized when Process/Contactor
switch is in an Electrode Hot posi-
tion and the engine is running.
Use switch to select weld process and
weld output on/off control (see table be-
low).

Place switch in Remote On/Off Switch
Required positions to turn weld output on
and off with a device connected to the
Remote 14 receptacle.
Place switch in Electrode Hot positions
for weld output to be on whenever the en-
gine is running.
Use Stick mode for air carbon arc
(CAC-A) cutting and gouging.
Use the Lift-Arc TIG mode for TIG
(GTAW) welding using the Lift-Arc TIG
starting procedure (see Section 6-7).
Place switch in MIG or FCAW position
for Smart Feeder option.
Typical Process Applications (DC Only)
